Abstract: A data processing apparatus produces electronic data from a document image in which a text part, a photograph part, etc. are mixed. This electronic data enables a user to display information in a required part. The apparatus extracts an object from an input image and integrates information on the extracted object and layout control information (script) for modifying a layout so as to generate integrated electronic data. A script program can be executed when the electronic data is used, which allows an object designated by a user to be magnified and rearranged so as to facilitate visualization of the object.

Abstract: A method for retrieving data includes a displaying step of displaying data including a plurality of attributes, a first selecting step of selecting a data segment functioning as a search key from the displayed data, a determining step of determining an attribute of the search key, and a searching step of searching a database by a search method corresponding to the determined attribute of the search key.

Abstract: In document recognition processing for accurately recognition a document image at high speed, a shape feature is extracted from a component included in an input document image, and the degree of similarity of shape between the document image and the registered document is calculated based on the extracted shape feature. When it is determined that the component of the document image has color information, the color information is extracted from the document image, thus calculating the degree of similarity of color information from the document image. The degree of similarity of shape is corrected based on the degree of similarity of color information, thus determining that the registered document is similar to the document image.
